MARKING DEVICE.

" Application filed March 26, 1927. Serial No. 178,730.

My invention relates to devices for -markingobj'ectsysuch a's cans, on aconveyor.

It is the'object of my invention to provide a marking device which maybe operated in conjunction witha conveyor at such a ratio of speed thatthe marking device will be timed with the rate of movement of acontinuous line of cans on .a conveyor so that each can may be markedwith a code or serial number. In such a device or mechanism it is myobject to provide novel arrangement and assembly of parts which will inan entirely automatic manner when properly set in time, withftheconveyor,gstainp each'can at the time when it is moved into alignmentwith the stamping device.v Q

The above and other objects which will be noted during the course of theensuing disclosure, I accomplish by that certain arrange ment andcombination of parts on which If have illustrated a preferredembodiment. i

Referring to the drawings: Figure'l is aplan view of the assembly withthe stamper bar in stamping position.

Figure 2 is a side elevation of the assembly with the stamper bar inre-inking position. i Figure 3 stamper" bar. V V

The conveyor on whichthe cans are carried is supported on standards 1.The mechanism which provides motive power for the conveyor is not shownas it forms no part of my invention. The conveyor has a track 2extending along it and a chain 3 having 'interspaced' lugs 4 which abutthe cans and cause them to move along on the track. The

stamping mechanism, which is illustrated, is adapted to stamp the end ofeach can as it arrives at a position aligned with the stamper bar.

The stamping device which we have shown is composed of a stamper bar 5carrying at one end a rubber stamp 6. The rubber stamp is moved by themechanism of the device from a position bearing against the end of a canto a substantially vertical position in which the stamp bears againstthe inking.

' pad 7 where during'each cycle of movement of the stamp is re-inked.

The mechanism which carries the stamp is supported usually from thefloor by angle supports 8. The stamping device has a head 9 to which thesupports are attached.

is aperspec'tive view of the The head is divided .into two sections andeach section has a curved groove 9 therein source of power which istimed with the rate of movement of the cans on the conveyor.

The sprocket 12 is mounted on a horizontal shaft 14 on which a beveledpinion 15 is i The pinion 15 engages a also mounted. bevel gear 16 whichis mounted on ashaft 17 extending through the side wall of the head andinto theopen space between the divided portions of the head. On theshaft 17 there is a short crank arm18 which is connected with a longlink 19. The link 19 is attached at its end opposite the connection withthe crahk,with the spindle'19 or axle of. the guide rollers 10.Referrin'g'to Figure 3 it will be observed that the link is connected toa forkedboss 20 which extends from one side of the stamper bar 5. Thusthe crank and link move the carriage for the stamper bar withoutcontrolling the angular position 7 of the stamper bar on the carriage.

The e'ndof thestamper bar opposite the part which holds the stamp isbifurcated as at 20 and a spring shaft '21-which extends through a hole22 in a plate 23 extended stamper bar, with relation to the carriage,

during its cycle of movement, is thus controlled. I have further foundit desirable to thread the shaft 21 and to mount thereon a, nut 26 whichprevents the shaft 21 from pulling the stamp-er .bar froin'the course ofits prescribed movement.

It will be apparent that other means of inking the stamp may be usedsuch as an inking roller, and the stamp may be made of any desiredmaterial. Further, other mechanical means for driving the stamper barwill readily occur to'those skilled in the art aside from theparticularstructure which I have illustrated.

The cycle of movement of the stamping device will be obvious. The crankand link move the stamper bar carriage up and down guiding membersextending the grooved supports at a rate timed with the rate of movementof cans on the conveyor and the spring shaft guides the staniiper barflhtlllftllo stamping position illustrated in Figure 1 to the reinkin;poe-ition shown in Figure 2.

Having thus dcacribed my invention what 1 claim as new and desire toi-ecure by Lettern ,la cut is:
